IMPROVEMENT IN TOOL-HANDLES.

Specification forming part of Letters Patent No. 142.56%, datedSeptember 9, 1873; application filed J une 24, 1873.

fand exact description ot' the same, reference `being had to theaccompanying drawings and to the letters of reference marked thereon.

The object of my invention is the construction of van easily-removabletool -handle particularly adapted for picks, adzes, and such tools,where a portion of the head or working part projects, in eitherdirection, beyond the line of the handle; and the invention thereinconsists in the construction and combination of the means employed forsecuring the handle to the tool, so that, `when in use, it shall b efirmly and rigidly attached to said tool, and be, at the same time,capable of ready removal therefrom. i

In order to better understand my invention, so that persons skilled inthe particular art may be enabled to construct the same,

' I proceed to describe the same, taking, for

convenience, a pick, and having reference to the drawings making a partof this speciication, in which- Figure l is a plan view of my device;Fig.

V2, a separate view of the tool detached; Fig.

8, a similar view of the holding strap or clip; Fig. 4, a view of thehandle with the holding strap or clip removed; Fig. 5, a verticalcentral longitudinal section of the device as ready for use.

Like letters of like kind denote similar parts in each figure.

In the drawings, A represents the head or working portion of a pick ofusual construction, except that ou the inner side, or that whiehcomesnext to the handle, it is recessed or cut away, which recess is shown ata. Upon and around the head of the handle B is a metallic coveringstrap, C, extending down the sides of the handle, and secured to thesame in any proper manner. That part of the coveringstrap which formsthe head of the handle projects beyond the wooden part of the same,leaving an opening, b, and is rectangular in outline, and of a sizewhich enables it to mit closely into the recess a in the tool. Withinthis opening/b, and to the inner side of the head of the covering strapC, is secured a metallic block, D, having a groove, c, on its underside; and, next in order below this, is another metallic block, E,having a groove, d, in its upper side, both of said grooves being of asize to receive atapering key, f, which passes between the blocks D andE. This block E has a transverse rib,

Ve, across its bottom, with dependent lockinglips f' at each end, andhas a length suiicient to enable such lips, in use, to lock into theholding strap or clip, not yet described. Next in order to the blocklast described is the block G, preferably of wood or other elasticmaterial, which rests upon the wooden portion of the handle. Openings gthrough the strap C, on either; side thereof, complete the descriptionof this part of my device.

The holding strap or clip H, of suitable material, passes over the heador working portion of the tool, and down over the sides of the handlenot covered by the strap G, and closes up the opening b; and hasitself', on either side, openings h, through which the lips f', beforedescribed, pass, and lock said strap on either side.

In putting together my device, the blocks E and G, being placed in theopening b, and the holding strap or clip H being sprung over the lipsf', the head Ais inserted between the strap H and the end of the strap Cuntil the recess aits upon the end of the strap G, when the key f isinserted through the openings g, and all the parts are firmly boundtogether. To take them apart is simply reversing the manner justdescribed. y

I am aware that a patent was granted March 29, 1859, to J. E. Emersonfor a tool-handle which has ageneral resemblance to mine, but differs inimportant particulars. handle the clip is fitted into a recess 4on theoutside of the tool, thereby brin ging the strain or shock, in use, uponthe clip. By my conA struction the strain or shock comes upon thehandle. It is, furthermore, believed that the recess upon the outsidetends to weaken the tool much more than the recess upon the inside, as Ihave it. In regard to the details of construction and arrangement of theseveral parts used in securing the handle to the tool, my de- InEmersons vice differs Widely from Einersons; which I, therefore disclaimas constituting.;` any part of my invention.

What I do claim, however, as my invention, and desire to secure byLetters Patent, is-

`1. The combination of the clip H, the tool A, provided with a recess,a, uponits inner side, and the strap G having its head constructed to tinto said recess, substantially as described and shown.

2. The combination of the clip H, the tool A, the strap G and the blocksG and E, the latter provided With the lips f', substantially asdescribed and shown.

This specification signed and witnessed this 16th day of June, 1873.
